The integrated circuit, U4083B, is a low power audio amplifier for a telephone loudspeaker. It has differential speaker outputs to maximize the output swing at low supply voltages. There is no need for coupler capacitors. The U4083B has an open loop gain of 80 dB whereas the closed loop gain is adjusted with two external resistors. A chip disable pin permits powering down and/or muting the input signal.
